1 3e` it known that I, ARTHUR y ,y citizen of the UnitedStates, residing at Topeka, inthe county lof Shawnee anditate of Kansas, have invented certain new land useful Improvements in `Engine Radiators;

and I do declarethe following to be a full,

. part of this specification. .15

clear, and exact description of the invention,

such as will enableothers skilledlin the art@ to which it appertains to make and use the same, reference being, had tothe accompanying drawings, and to the letters and figures of reference marked thereon, which form a This invention relates to engine cooling systems in which a cooling fluid is circulated through a vwater "jacket surrounding the l to be cooled. 20,`

the cooling jacket power cylinder-for other part of the engine l `The generic principle of a water cooling system xls well known as involving a water ljacket, a source of heat radiation vor heat dissipation, `and ian impell'er,l usually a pump, forinducing circulation ofthe iiuid through the system," including` the` radiator,

1'and the connections betweenthe same. l

The present invention' contemplates the provisionl of' means whereby the [ly wheel of the engine vmay be `utiliaed as they heat `dissipating element and-infowlerto induce cir;

` p `culation through the fly wheel andthrough i the water jacket,` I have `Tnfovided 4an 1mpellerin the circulating system. `The imf' peller has movement in response to movement of the fly wheel and one of thefleatures `of Imy invention is the novel, convenient and easily accessible construction of "impeller" so associated with fthe fly wheel that access may be had :thereto yfor `the purpose of" inspection or repa1rs,.the organization being such that ease of assemblage as well'as 'simplicity of` manufacture is providedfor.

vertical type of stationary, reciprocatory gas engine which may be of any preferred con-y struction and which is provided with a water jacket 1 about the power generating cylinder or cylinders 2 above the crank case if supported upon the base 4. 'y

- The'usual crankshaft 5 carries a rotating radiator which also constitutes the fly wheel. The radiator is shown as provided with a split `hub (ikeyed to the shaft as at and further fastened by the bolt 8.`

` The` radial spokes 9 on the hub support arim 10 consisting of a peripheral flange havingxa'circular series of lateral slots 11.

The flange 10 provides a recess or pocket about the hub V6, within `which is received a heat dissipating radiator consisting of ring laminations 12 spaced apart and supporting U-shaped tubes y 13 passing through them, and through which the cooling` waterfinay circulate to permit air entering the recessed flywheel to contact `with the tubes and the `laminations'and carry off the heat through projecting inwardly `beyond the inner edges of thelaminations 12, as clearly indicated in Figs. I and III.

"Iyhereis also a ,ofythe wheel and said head is provided `with an off-set flange 17 of substantially the samediameter as that of the ring and of therim 10 so that the flange may clamp the ring 15 between it andthe edge 14, there being preferably a packing 18 providedbetween the `flange 17 and ring 15, as shown in Fig. I. l y i 1 The fastening devices for `effecting the securing of the partsy together are shown as bolts `19, (Fig. I) so that the radiator may be held in place. i y `'Ihehead 16is providetl on its inner face with circumferential beadsor flanges 20 and 21adapted tobear against the plate 15 to provide circulating passages22 and 23. The bead or iiange 21 `is'adaptedto kbe clamped head 16 for closing oneside ioo l tothe inner' portion of the ring 15 by a packed joint consisting` ot the packing 24 and the clamping ring 25, there being bolts 26 provided which pass through the clamping ring 25, the plate 15, the packing 24 and enter the threaded opening in the bead or and' communicating with the passage 23 through the medium of a radial port 30 shown as diametrically opposite the port 28. The ysleeve portion 27 oit the hub is provided With external threads 31 and with an internal shoulder 32, the shoulder being adapted to rest upon the sleeve bearing 33' of the impeller housing or casing 34, concentric with the iy Wheel and head. The bearing or impeller member 33 extends into the sleeve 27 and a joint is provided by the gland or packing 35, clearly shown in Fig. I.

The end of the tubular member 29 is provided with a shoulder 36 and a constricted, threaded neck or end 37. Vhen the impeller casing is connected to the sleeve 27, the inner edge of one wall 38 will rest upon the tubular member 29, permitting the restricted portion 37 to extend into the casing toreceive the` hubj39` of the impeller comprising the hub, a disk 40 secured to the hub, and blades 40 secured to and extending at right angles to the disk. The impeller hub 39 may rest against the shoulder 36 and be secured :tast

- to the tubular member or shaft 29 through the medium et a fastening device, shown as a nut 41. The impeller housing may be closed by a cover member 42 secured to the housing by fastening devices 43, as will be1 apparent by reference to Fig. I.

There is a radial port 44 carried by the casing 34 which communicates directly with the chamber 45 formed by the members 29 and 33 and this port is adaptedto communicate with the outlet 46 of the water jacket 1 through the medium of a conduit or pipe 47, the outlet port 48 for the casing 34- being adapted to communicate with the inlet port 49 of the water jacket 1 through the medium ot' a pipe or conduit 50.

'A Then the parts' are assembled and the crank shaft 5 rotates, the iluid will pass from the top ot' the water jacket through port 44 into the chamber formed by 27, 33

and 29, and through the port 28 into the .chamberor recess 22. There the water will pass through the :1U-tubes 33 into the chamber or recess 23, through port 30 into the passage formed ,by the tubular member 29 the {iuid in the casing 34 to torce it through pipe 50 and through the inlet port ot the water jacket, further inducing circulation.

Therefore, it will be seen that as the engine operates, the fly wheel and radiator will rotate, causing a continuous circulation oi the cooling fluid within the iiy wheel and the impeller in the casing 34.

When it is desired to inspect the interior ot the fly wheel radiator or the impeller ior any purpose, it will be only necessary to take oi'l the plate 42, loosen the packing gland 35 whereupon the impeller casing may be separated from the ily wheel upon removal of the nut 41.

It will also be apparent that the mechanism is such that it can be readily assembled without complicated tools or especially skilled labor.

The manner of circulating thc air will be apparent by reference to the drawings. from which it will be seen that the air will enter between the spokes 9 and pass between the laminations, over the tubes 13, and out through the slots 11, dissipating the heat absorbed by the iluid as it passes through the water jacket.

Of course, in actual practice, it is asscntial that some means be provided for anchoring the impeller casing, the particular means being unimportant. However, :for convenience I have shown the impeller casing as anchored to the base plate 5 by a standard or rod 52, which engages the perforate lugs 53 on the impeller casing 34.

What I cl aim and desire to secure by Letters-Patent is: n 1. The combination of a rotating radiator, an impeller casing communicating with the radiator, a ported impeller shaft within the impeller casing and in ported connnunication with the rotating radiator. and an impeller thereon, said impeller casing and impeller being distant from but concentric with the rotating` radiator.

2. The combination of a fly wheel with a radiator carried by the ily wheel having ports through whichv a [luid may circulate, an impeller casing communimxting with the ports in the radiator and concentric therewith, a shaft integral with the radiator and extending into the impeller casing.

3. A fly wheel having a peripherally slotted rim, la radiator witl'lin the fly wheel comprising vlaminations and transverse. U- shaped tubes passing through the laminations. a head on the iiy wheel having chambers communicating with the opposite ends of the U-shaped tubes, an impeller casing communicating with the ports in the head, said impeller casing being remote trom but concentric with the head, means for removably connecting the impeller casing and thc head together. an impeller within the casing receiving motion from the head. 'A

4. rotating radiator frame having a peripheral flange, a radiator comprising a wplate of substantially the same diameter as M i the frame, radiator' tubes carried by said plate, `a headrn`eans `for clamping the radiai tor` platebetween the flange and the head,

`said head being provided with inlet and outlet ports communicating with opposite ends of the radiator tubes, an impeller casing distant rombut concentric with the head, a

concentric impeller within the casing and` carried by apart of the head whereby when the impeller.

j ripheral Hangs, a radiator element carried by the frame, said radiator element comprisf the head rotates, motion will be imparted to 5.V A rotating radiatorl frame having a peing a plate substantially equal in diameter to the diameter of the frame, radiator tubes carried by the plate, a" heacl `hauling peripheral grooves providing water chambers, n radial ports in `thehead communicatingwith y the respective water chambers, means 'for `leaving a watercharnber communicating with the respective ends of said tubes, a hollow hub on said head communicating with one of the chambers, a `concentric shaft within the hub communicating with the `other chamber, the shaft extending beyond the end of the hub, an impeller casing having a sleeve engaging the hub, a packinggland constituting` a water-tight connection between the hub and thesleeve, an impeller on the end of :the hollow shaft. y i

In testimony whereof I afiix my signature.
